I want to set up a pure home music server and control via “messaging” from my PH server the sound level/mute states of the music.
Can this be done? If necessary I can install PH on the music server but it will control nothing but only accept sound control messages.
Can this music server be installed and run without a connected PLM?

Ken,

I regularly communicated with external devices directly to/from PH.
I communicate with my Raspberry Pi's and all my Shelly Devices using this method.
This method is simple and reliable and doesn't require any controllers or hubs.
Straight HTTP.
(I have been replacing all my x10 devices with Shelly devices. They are fantastic!)

To "get into PH" from an external device you can use this command directly from a browser or device to test:
http://192.168.x.y:PH_PORT/ph-cgi/eval?formula=ph_macroparm( "Name_of_PH_macro", "into_local1", "into_local2","into_local3","into_local4","into_local5")', auth=(PH_USER, PH_PASSWORD )
You must have all 5 "into_locals" or the PH formula will error out.

If you use ph_macroparmret() rather than ph_macroparm() you can get back a response from PH to the device.
Whatever is put into PH local1 when the PH macro ends will be sent back to the device.

There's no reason you couldn't talk to/from another PH or any device that can send/receive HTTP requests.

Hope this helps.
If you want more detailed info I can help.
I can show you my Raspberry Pi code, or the PH code to "talk to" the Shelly devices.
